The active ingredient — hydrogen peroxide or carbamide peroxide — penetrates the enamel and dentin to oxidize the chromophores (color-causing compounds) that accumulate from food, beverages, tobacco, and aging. The key difference between professional and over-the-counter whitening is concentration. Professional in-office systems use 25–40% hydrogen peroxide, compared to 3–10% in OT
